  3. 3. Introduction • Digital reference (or virtual reference) is a service by which a library reference service is conducted online, and the reference transaction is a computer-mediated communication. It is the remote, computer-mediated delivery of reference information provided by library professionals to users who cannot access or do not want face-to-face communication. Virtual reference service is most often an extension of a library's existing reference service program. The word "reference" in this context refers to the task of providing assistance to library users in finding information, answering questions, and otherwise fulfilling users’ information needs. Reference work often but not always involves using reference works, such as dictionaries, encyclopedias, etc. This form of reference work expands reference services from the physical reference desk to a "virtual" reference desk where the patron could be writing from home, work or a variety of other locations. • The terminology surrounding virtual reference services may involve multiple terms used for the same definition.[1] The preferred term for remotely delivered, computer-mediated reference services is "virtual reference", with the secondary non-preferred term "digital reference" having gone out of use in recent years. "Chat reference" is often used interchangeably with virtual reference, although it represents only one aspect of virtual reference. Virtual reference includes the use of both synchronous (i.e., IM, videoconferencing) and asynchronous communication (i.e., texting and email). Here, "synchronous virtual reference" refers to any real-time computer- mediated communication between patron and information professional. Asynchronous virtual reference is all computer-mediated communication that is sent and received at different times.
  4. 4. Dr. S R Ranganathan, “reference service is a personal service to each reader in helping him to find the documents answering his interest at the moment pin pointedly, exhaustively and expeditiously”. In his view, providing reference service means making contact between the right user and the right book at the right time and in the right personal way. CA Bunge says, “Reference service, some times referred to as reference and information service, which refers to the personal assistance provided to the information seekers in the pursuit of information”. Further, he categorized the reference service in the following three broader categories:
  5. 5. Types of Digital Reference services • E-Mail Reference Service. • Real Time Digital Reference Service.
  6. 6. E-Mail Reference Service The e-Mail reference transaction involves back-and-forth exchange of information, users would not get any immediate answer. But users can ask a question when they think of it, at any time of the day or night. And they do not have to take time to make a special trip to the library. In other words, the users send e-mail to the library with a reference question, asking whatever information they feel necessary. The library sends reply by e-mail, fax, phone or letter as it finds convenient. In such a case, the controller of all questions initially receives and examines and then routes them to appropriate staff. Technical questions are forwarded to technical staff, circulation related questions to the circulation staff, reference questions to the reference librarian, and so on.
  7. 7. Advantages • Who feel shy and uneasy about asking questions in person, face-to-face or by telephone. • Who are poor in oral communication. • Who may not be able to visit library due to certain difficulties in physical movement, living at a long distance from the library, and so on.
  8. 8. Disadvantages • Reference librarian cannot establish eye contact or conduct face-to-face reference interview to seek any clarification with the user. • It is difficult to judge the urgency of the requirement of information. • To know the degree of the user’s satisfaction for further modification of searchstrategy for providing more relevant answer. • Speed of asking a question and getting an answer depends upon the volume of email traffic and communication link over the Internet. • Reference librarian needs to make more efforts in understanding the meaning of the asked question. Sometimes, he misses the focus of the asked question because users often do not clearly express the question.
  9. 9. E-mail reference service Advantages for the reference librarian . I. Reference librarian finds more time to think, plan, chalk out search strategy and finally search the answer. II. Simple or easy questions can also be answered by other staff. III. Reference librarian can devote more time on questions of complex nature. IV. This way the workload of reference process can be distributed among other staff. V. Question can also be diverted to the experts, if required. VI. There is no restriction on working time. Question can be answered any time after working hours. VII. This mode of receiving and answering questions is very cost-effective
  10. 10. Real Time Digital Reference Service In real time digital reference service, the exchange of information is live (it takes place in real time) between user and reference librarian. This service is still on experimental stage in developing countries because it requires advanced computer technology, faster and better communication connectivity, interactive audio and video capacity and availability of computers at home and work place. This service is not a replacement of conventional or e-mail reference service but a supplement to these services.
  11. 11. Advantages • This is a synchronous service in which reference librarian responds immediately in • real time. • Reference interview is conducted at a faster pace than e-mail. • Clarification can be sought online. Reference librarian can demonstrate to the user about how to use reference sources, • web sites, expert or whom the user should contact. This allows user to walk through • the reference source to find answer. In addition to this, Voice Over Internet Protocol • (VOIP) allows reference librarian to talk to users and hear them while connected • and while locating the sources. • This service can be offered at any time, any day (24/7 basis). • Reference librarian can chat with several persons simultaneously.
  12. 12. Disadvantages • The technology is still at premature stage. • It is a labour-intensive service. • It makes reference librarian busy in answering the questions because it involves • several back-and-forth message transactions. He may not find time to answer the • urgently needed questions. • It is stressful for reference librarian as well as user because one is waiting for • other’s message. • For every inquiry, user needs to type questions every time and reference librarian • also need to answer in typed form. • Typing speed and errors occurring during typing in the text cause, both reference • librarian and user, difficulties in communicating their messages because real time • chating demands fast and accurate typing speed.
  13. 13. Real Time Digital Reference Technologies: • 24/7 Reference • • AOL Instant Messenger • ConferenceRoom • Desktop Streaming • DigiChat • eGain Live • e-Gain Voice • Group Board • HumanClick • LiveAssistance • Livehelper • LivePerson • NetMeeting • Reference Services • 273 • Netscape IRC • OnDemand • QuestionPoint • Rakim • RightNow Live • Virtual Reference Software
  14. 14. MAJOR DIGITAL REFERENCE SERVICES PROJECTS • Collaborative Digital Reference Service (CDRS) • Automatic Reference Librarians for the World Wide Web • Virtual Reference Desk (VRD) • 24/7 Reference
  15. 15. Digital reference services: challenges • Chat has some negative aspects for digital reference which makes it problematic to operate. Question negotiation, for example, is difficult since the librarian has little knowledge of the user’s status and is short of nonverbal cues. It is also difficult to control interview time effectively in a digital conversation. • Cost: both software and staff time are expensive. It is stated that there would be a large increase in workload when digital reference is fully utilized [ It is also questionable whether it is economic to have somebody wait for a question 24/7 when most questions occur within regular office hours.
  16. 16. Cont.. Collaboration: Theoretically it would be ideal to let users throughout the world benefit from the knowledge of professionals around the globe. However, firstly, we need to question whether this is necessary at the moment. Coffman doubted the necessity of collaborative digital reference. He stated, “based on the data I’ve seen, the likely explanation is that with easy access to online resources, most libraries now have everything they need to answer the vast majority of questions they get on their own” . Secondly, is it practicable or feasible? Due to the proliferation of institution specific questions and language issues the meaning of collaboration across institutions and even throughout the world is debatable. The great difference between academic libraries and public libraries makes cross-spectral cooperation difficult.
  17. 17. Conclusion After the search I found that Many Libraries and Information Centre using this service are maintain to digital collections and provide information in digital/ electronic mode. With the emergence of digital libraries and Internet, the concept of traditional reference service has changed. Even many non-library commercial organizations now offering digital reference service to their clientele. While some are free, others need payment. In digital reference service, the web is used as a medium of communication for sending the questions and receiving answers, which is quite useful in providing fast answers to the questions. However, the reference librarian needs different skills for accessing digital information sources and communicating the information to the users. Digital references services is very important tools of every references librarian.
